    摘要： A percutaneously implantable device for the treatment of a cardiac condition or other disease is disclosed herein, the device capable of delivery and maintenance of a therapeutic scaffold. A therapeutic scaffold may comprise viable tissue to impart or restore normal cardiac function, or other therapeutic agent for the treatment of disease or injury. Viable tissue may comprise a pacemaker gene or other genes intended to impart a pacemaker function to either host tissue or transplanted tissue, or both. Further, a device according to the invention may be used for the implantation and maintenance of viable tissue to induce or enhance muscle contraction of a subject for the treatment of a disease or disorder.

    摘要： A method and gene therapy agent for treating a vulnerable plaque associated with a blood vessel of a patient is disclosed. The method includes providing at least one gene therapy agent encoding at least one protein. The gene therapy agent is administered to a target cell population. The protein is expressed within the patient from a portion of the target cell population. The vulnerable plaque is modified as a result of the protein expression. The gene therapy agent includes at least one polynucleic acid encoding at least one protein. Administration of the gene therapy agent to a target cell population results in expression of the protein capable of modifying the vulnerable plaque.

    摘要： Provided are devices and methods for treating or preventing smooth muscle cell proliferation caused by endothelin-mediated conditions. In particular, a medical device comprising a structure which is implantable within a body lumen and means on or within the structure for releasing an endothelin (A) receptor antagonist at a rate effective to inhibit smooth muscle cell proliferation. The device can be, for example, an expansible stent or a graft, and the means can include a matrix coating, wherein the endothelin (A) receptor antagonist can be dispersed within the coating or disposed directly on the structure and under the matrix. The methods and devices of this invention can be used to decrease the incidence of restenosis as well as other thromboembolic complications resulting from implantation of medical devices.

    摘要： The gradient coated stent 150 of the present invention provides a coated stent having a continuous coating 130 disposed on the stent elements. The continuous coating 130 includes a first coating component and a second coating component. The concentration of the first coating component varies continuously over at least part of the thickness of the continuous coating 130. The concentration of the second coating component can also vary over at least part of the thickness of the continuous coating 130. In one embodiment, the concentration of the first coating component decreases in the direction from the stent element towards the outer edge of the continuous coating 130 and the concentration of the second coating component increases in the direction from the stent element towards the outer edge of the continuous coating 130.

The anti-restenotic protein-tyrosine kinase inhibitor is 4+4-Methyl-1-piperazinyl)methyl]-N-[4-methyl-3-[[4-(3-pyridinyl)-2pyrimidinyl]amino]-phenyl]benzamide methanesulfonate and pharmaceutically acceptable derivatives thereof (imatinib mesylate). The anti-restenotic medial devices include stents, catheters, micro-particles, probes and vascular grafts. The medical devices can be coated using any method known in the art including compounding the protein-tyrosine kinase inhibitor with a biocompatible polymer prior to applying the coating. Moreover, medical devices composed entirely of biocompatible polymer-protein-tyrosine kinase inhibitor blends are disclosed. Additionally, medical devices having a coating comprising at least one proteintyrosine kinase inhibitor in combination with at least one additional therapeutic agent are also disclosed. Furthermore, related methods of using and making the antirestenotic implantable devices are also disclosed.
